PROBLEM TO BE SOLVED: To prevent a waste gasification combustion system from generating or discharging toxic substances, such as CO, DXN, NOx and the like, even if there is fluctuations in the feeding amount or calorie of waste, by making the feeding amount of waste or a combustion improver controllable, in response thereto to keep a furnace load constant in the melting furnace and the like for complete combustion. SOLUTION: The waste gasification combustion system comprises a thermal decomposition furnace for pyrolizing waste, a melting furnace for melting ashes and the like by the thermally decomposed gas and a secondary combustion chamber provided downstream from the melting furnace. It further comprises a waste-feeding amount adjustor for adjusting the feeding amount of waste, of CO concentration detector for detecting the CO concentration in a gas channel, and a controller for comparing the detected CO concentration in the gas channel with the tolerance thereof and outputting an adjusting signal for the feeding amount of waste, based on the compared results such that the CO concentration in the gas channel becomes smaller than the tolerance.
